Procedure

Combine 4-(2-hydroxy-ethyl)-phenol (2.0 g, 14.5 mmol), 6-chloronicotinamide (2.3 g, 14.5 mmol) and K2CO3 (5.0 g, 36.2 mmol) in DMF (40 mL) under nitrogen, stir and heat at 120° C. overnight. Cool to ambient temperature and pour into water, extract the aqueous layer with ethyl acetate. Combine the organic layers and dry over Na2SO4. Eliminate the solvent and purify by flash chromatography on silica gel (eluent: CHCl3/7% EtOH/0.7% NH4OH) to give the title compound (1.8 g, 49%). Electrospray MS M+1 ion=259, 1H-NMR (DMSO-d6, 400 MHz): 8.58 (d, 1H, J=2.7 Hz), 8.22 (dd, 1H, J=2.7 and 8.8 Hz), 8.00 (bs, 1H), 7.46 (bs, 1H), 7.25 (m, 2H), 7.05-7.02 (m, 3H), 4.65 (t, 1H), J=5.3 Hz), 3.63-3.58 (m, 2H), 2.72 (t, 2H, J=6.9 Hz).
